The ON Semiconductor NCP1421DMR2G is a monolithic micropower high-frequency step-up switching converter IC. It is designed for battery-operated handheld electronic products and can handle loads up to 600 mA. The device integrates Sync-Rect for improved efficiency and eliminates the need for an external Schottky diode.
Key electrical specifications include an adjustable output voltage range, a high switching frequency of up to 1.2 MHz, and a current limit of 1.5A (switch). It offers high efficiency, with up to 94% for a 3.3V output at 200mA from a 2.5V input. The device also features a true-cutoff function that reduces shutdown current to typically 50 nA and a low quiescent current of 8.5 µA.
This boost converter is available in a compact 8-MSOP package, suitable for space-constrained designs. It operates over a temperature range of -40°C to 85°C. Typical applications include personal digital assistants, handheld digital audio products, and white LED flash for digital cameras.
